Perhaps you’re eating “al desko” and overhear a coworker’s conversation about having to call her “deso” after getting “ghosted” by her “health goth” boyfriend last night. You might be down with the lingo or you might be sitting there holding your ham sandwich (or “sammy,” as the kids say) like, “What the what?”

For those who have already adopted this lexicon, your vocabulary has been legitimized and you can go back to swiping right. If you’re still trying to figure out what your 17-year-old means when everything she says just sounds like nonsense, Dictionary.com has added 300 new words and definitions and over 1,700 updated entries, according to the online dictionary.
